This is certainly one takeaway. On the other hand, this very blog post points out that a community member, Dzmitry Malyshau, did the work to get the program working on the OS he uses. Malyshau does not work for Zed, which is a for-profit company; as far as I can see, he gets nothing out of working on Zed, except that he and other Linux users get to use it. Perhaps, rather than characterizing Linux users as whiny, we could take away the idea that many Linux users are willing to put in quite a lot of work to make things better for each other.
